A good idea for a block would be a recall device. this would allow you to have unmaned drones that can go out to fight and then return to your ship/space station when the battle is over or you want to run. have two blocks, a master control or "Recall Computer" which you connect to the "Recall Device" blocks and when you activate the Computer you can recall individual units/ships or all at once. it should also be able to have them dock.
Say they have you have a docking module then it should be able to automatically dock to your ship to share its sheilds, cloak, jammer and thrust.
